DRAFTLBAR. n

To all whom timely concern? Be itjknown that I, 'GEORGE A. H1LLER,acitizen of the UnitedStates, and resident of East Rochester, in thecounty ofv Monroe and State of New York, have inventedcertain new anduseful improvements Draftn Bars', of which the following is aspecification.l e

The present' invention relates to 'draft bars of the type lemployed forconnecting L two vehicles. so thaton'e may be drawn by the other, an-object of this ,invention being to provide astrong and durablestructure which shall have a minimum weight.'

To this and other ends, the Vinvention, con sists of certain partsandconrbinations of parts. all of which will be hereinafter ydescribed,lthe novel features being pointed out "in the appendedl claims.

ln 4the drawings Figure l is a plan view of the-draft'bar; Fig.j2 is asideview; j 1 Fig. 3 is anenlarged view partially in section v Fig. 4is'a. perspective view of one ofthe transverse brace plates before it isapplied; Fig. 5 is lan enlarged transverse section, through the draftbaron the line 5-5, Fig. 1, showing one ofl the transverse plates beforeit is fastened tothe bar; and Fig. 6 is a view similar to 5, showingthebrace plate secured to the draft bar.

'According to the illustrated embodiment of this invention, the draftbar comprises a strip of flat stock bent between its'A ends at 1 to formtwo diverging arms 2, said stock being provided with an opening 3 at thebend 1, and with openings 4 at its free end, the openings 4 beingaxially alined. Between its ends the arms or diverging portions 2 may bebent slightly edgewlse of the stock, as at 5 and 6, in order that whenASpecification of' Letters Patent.,

Application i'ledDecember12, 1918. vS.eral1115.266482 y plates-*having recessed sides 11 formingtongues 12 on opposite sides of the recesses; These recesses receive thediverging portions 2,-and the tongues y12,1formedby the recesses', are4bent over vthe outer facesofthe diverg# ing'portio-ns 2 in the mannershown at 13 y in Fig. y6, after which all of the contacting faces ofthebrace plates or pieces 10 vare welded to the diverging portions 2. Thesebrace plates are each provided with an opening or'slot`f'14, yand anropening or slot 15 is provided in the connection between the arms andthe UAshaped piece? y"lhroug'hthe openings 14 and theopening 15 as wellas the opening3 in the bend 1 of tlie`fflz`tt'stock 12, a longitudinallyextending brace piece 1-6 is arranged. Thislongitudinally'extendingbrace piece is 'prefera-k bly also'inade of flatstock, and its .faces are perpendicular to the flat -facesof the flatstock .forming the diverging portions 2. The longitudinally extendingbracepi'ece 16 is y'welded to each of the braceblocks, as well as to theU-shaped piece 7 and to the bend 1 of theflat; stock forming thediverging portions 2; y l -f Near the bend 1 the"longitudinallyfexLtending 'brace piece 16 may be provided with two openings 17' throughwhich .are passed bolts v18, which are employed for securing Va'clip 19.A"This clip Inaybe formedofa body part having a projection 20 receivedbetween the diverging portions 2 adjacent the bend 1, this projectionabutting the bend and the opposed inner faces of the diverg-l ingportions 2 on the upper side of the brace piece 16. A removable piece 21is heldsto the body part 19 by the bolts 18, and fits snugly on theunder side of the longitudinally-extending brace piece 16 in abutmentwith said brace piece, the bend l, and the faces of the divergingportions 2.' A shackle 22 may be pivotally connected at 23 to the clip19 for connection with another vehicle.

From the foregoing it will be seen that there has been provided a strongand durable structure of light skeleton formation. This structure, inthis instance, is made entirely from flat stock and the pieces areformed and arranged so that -the tendency to bend the bar, due tolateral stresses, is overcome.

A draft bar comprising. a strip bentbetween its ends to form two diverging portions,'a U-sha-ped piece ttedbetween the vfree ends of the fiat stock, transverse brace the twodiverging portions,l and a longitudinallyextending pieces connectingbrace piece arranged between the diverginojportions connected at oneendto the U- aped piece, at its other end to the stripv at the bend, andbetween its ends to the transverse i brace pieces. g t

2. A draft bar comprising two diverging portions, a longitudinallyextending brace piece arranged between the divergingportions, andtransverse brace pieces connecting the diverging portions and havingopen'- ings through which the longitudinally extending braceY pieceextends, said longitudinally extending brace piece being securedto saidtransversely extending brace pieces.`

3. A draftbar comprising a strap bent between its ends to provide'twolongitudinally extending pieces, transverse brace pieces connecting saidlongitudinally extending pieces, and a longitudinally extending bracepiece connected to said transverse brace pieces and alsoconnectedto'thestrap at thebend.
